Now I am not sure what you did.
You said "deleted all pix on camera with the apple after".
I expected to see "using a card reader on the computer, I deleted all files and folders on the memory card".
Not just photos but ....
This time delete ALL files and folders you find on the memory card, using a card reader on the computer.
This has always worked for me on my PC computers.
But you are using an apple computer.
It may do things differently.
Maybe someone familiar with an Apple computer will have some ideas.
